Safety Precautions

This user manual contains the information concerning the installation and operation of Liebert® ITA 10kVA UPS

(hereinafter referred to as UPS).

Please carefully read this user manual prior to installation.

Warning

1. The UPS must be installed and commissioned by engineers designated by the manufacturer or its agent. Failure to

observe this could result in personnel safety risk, UPS malfunction and invalidation of warranty.

2. The UPS has been designed for commercial and industrial use only, and is not recommended for use in life support

applications.

3. This is a Class A UPS product. In a residential environment, this product may nevertheless cause radio interference, in

that case, the user is required to take additional measures to reduce the interference.

4. Never dispose of the battery module in a fire because it may explode and endanger personnel safety when exposed to

flame.

Note

1. The standard UPS has the external battery module, the output terminals of the UPS may carry live voltage even when

the UPS is not connected to AC mains.

2. Before moving or re-wiring the UPS, disconnect all the inputs and make sure that the UPS is completely shutdown. Or

else, the output end may carry live voltage.

3. The operating environment and the storage method will affect the life and reliability of the UPS, it is not recommented to

use the UPS for a long time in the following environments:

 Places where the temperature and relative humidity are outside the technical specification (temperature: 0°C ~ 40°C,

relative humidity: 5%RH ~ 95%RH).

 Places where direct sunlight and near heat source are present.

 Places where vibrations or shocks are present.

 Places where dusty, corrosive substances, salts or flammable gases are present.

4. Keep the air inlet and outlet well-ventilated. Poor ventilation will increase the internal temperature, which will shorten the

life of the UPS components and that of the UPS.

5. Liquid or other irrelevant external objects are prohibited inside the UPS.

6. In case of a fire, a dry chemical fire extinguisher is essential. Using a foam fire extinguisher will cause an electric shock.

7. The life of the battery module will be shortened with the rise of the ambient temperature. To ensusre noraml UPS

operation and enough back-up time, the battery module should be replaced periodically. Only Emerson-authorized

technicians are permitted to replace the battery module.

8. If the UPS will remain idle for a long time, it must be stored in a dry environment. The storage temperature should be

-20°C ~ +55°C for standard UPS (with battery modules), and be -40°C ~ +70°C for long back-up UPS (with no battery

modules).

9. The UPS is a professional equipment with a total rated power larger than 1kW. The equipment complies with IEC

61000-3-12 provided that the short-circuit ratio is larger than or equal to 250 at the interface point between the user’s power

supply and the power grid. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the

power supply department if necessary, that the UPS is connected only to a power supply with a short-circuit ratio Rsce

larger than or equal to 250.

10. The UPS output cable must be not longer than 10m.

11. The backfeed protection unit is external. For the using method, refer to UF-BFP-63A Backfeed Protection Unit User

Manual.

12. In Normal mode, the output neutral line of the UPS is connected with the input neutral line. Upon the mains failure, the

output neutral line will be suspended, which results in the output neutral line unconnected.

Components behind the protective cover which can only be removed by using a tool are restricted to service personnel.

2. The UPS meets the safety requirements completely in operator access area. Only service personnel can contact with the

hazardous voltage inside the UPS. However, the risk of contacting these voltages is minimized because the components

with hazardous voltage may be contacted only by using a tool to remove the protective cover. No risk will exist if you follow

the general norms and in accordance with the procedures recommended in this manual on equipment operation.

Warning: battery high voltage

1. All the physical service and maintenance of the battery are performed by the trained technicians.

2. Operation on the battery will result in electric shock and high short-circuit current, therefore, before operating the battery,

the following should be observed:

 Remove the watches, rings and other metal objects.

 Use the tools with insulation handle.

Figure 1-4 UPS operating principle

1. The UPS is composed of mains input, I/O filter, rectifier/PFC, inverter, bypass, internal charger, battery input and

UPS output.

2. When the mains is normal, close the bypass MCB, and the internal charger will charge the battery. Before the UPS

is turned on, the output voltage is zero. After the UPS is turned on, the electronic transfer switch connects the inverter

to the load, and the mains supplies DC power to the inverter through the rectifier/PFC circuit. The inverter then

converts DC power into pure sine wave AC power, and supplies the AC power to the load through the electronic

transfer switch.

3. When the mains is abnormal, the rectifier/PFC circuit boosts the battery voltage and supplies it to the inverter. The

inverter then converts it into pure sine wave AC power, and supplies the AC power to the load through the electronic

transfer switch.

4. After the mains restores, the UPS will automatically transfer from Battery mode to Normal mode, the mains

supplies DC power to the inverter through the rectifier/PFC circuit, and then the electronic transfer switch supplies the

AC power to the load.

1.5 UPS State And Operation Mode

The UPS state and operation mode include: Normal mode, Bypass mode, Battery mode, ECO mode, Fault state and

Maintenance Bypass mode.

The operation schematic diagrams of Normal mode, Bypass mode, Battery mode and Maintenance Bypass mode are

shown in Figure 1-5.

Note

Only when the UPS output power distribution unit (POD for short) is configured, the Maintenance Bypass mode is valid.

4 Chapter 1 Product Introduction

Liebert® ITA 10kVA UPS User Manual

Normal mode Bypass mode

Battery mode Maintenance Bypass mode

Figure 1-5 Operation schematic diagram

1.5.1 Normal Mode

When the mains input is normal, the load is supplied with voltage-stabilizing and frequency-stabilizing power by the

mains after processing of the rectifier and the inverter, and meanwhile, the charger is charging the battery, the

operation mode is Normal mode. In Normal mode, the mains indicator and the inverter indicator are on.

1.5.2 Bypass Mode

If the overload overtime, inverter or rectifier fault appears during the UPS operation in Normal mode, the UPS will

transfer to Bypass mode, that is, the load is powered by the bypass source, which comes directly from the mains

input. If the rectifier is normal, the internal charger will charge the battery. In Bypass mode, the inverter indicator is off;

the mains indicator and the inverter indicator are on.

Note

In case of mains failure or mains voltage out of range (120Vac ~ 253/264/276Vac) in Bypass mode, the UPS will turn off and stop

the output.

Chapter 1 Product Introduction 5

Liebert® ITA 10kVA UPS User Manual

1.5.3 Battery Mode

Upon mains failure, rectifier overload or mains voltage out of range (120Vac ~ 288Vac), the rectifier and the internal

charger will stop running, and the battery will supply power to the load through the inverter. The battery indicator and

the inverter indicator are on, and the buzzer alarms every 3.3 seconds, which notifies you that the UPS is in Battery

mode.

Note

1. The battery has been fully charged before delivery. However, transportation and storage will inevitably cause some capacity

loss. Therefore, it is required to charge the battery for eight hours before the UPS is put into operation for the first time, to ensure

the adequate back-up time for the battery.

2. The battery cold start can also be used to start the UPS from Battery (charged) mode upon mains failure. Therefore, the

battery power can be used independently for improving the system availability to some extent.

3. In Battery mode, when the battery voltage is low, the buzzer beeps rapidly (once per second), and the corresponding

measures must be done in time.

1.5.4 ECO Mode

In ECO mode, when the bypass voltage is within 220Vac ± 10% and the frequency is within 50Hz ± 2Hz, the load is

supplied by the bypass and the bypass indicator is on. When the bypass voltage is abnormal, the load is supplied by

the inverter. The ECO mode is an energy-saving operation mode. For power equipment insensitive to power grid

quality, you can use ECO mode for power supply through the bypass to reduce the power loss.

When the bypass voltage is normal, the inverter is in no-load state. The load is supplied by the bypass and the

bypass indicator is on.

Note

1. In ECO mode, if the bypass failure or abnormal bypass voltage appears when the output is not overloaded, the UPS will

transfer to Normal mode. However, if the bypass failure or abnormal bypass voltage appears when the output is overloaded, the

UPS will not transfer to Normal mode, but will shut down the bypass.

2. In ECO mode, the efficiency of the UPS is up to 97%.

3. Different voltage types have different voltages and frenency ranges.

1.5.5 Fault State

In Normal mode, the UPS will transfer to the Bypass mode if the inverter failure or UPS overtemperature appears. In

Battery mode (with no bypass mains), the UPS will turn off and stop the output if the inverter failure or UPS

overtemperature appears. If a UPS failure occurs, the fault indicators will turn on, the buzzer will keep beeping, and

the corresponding indicator will blink.

Note

In Fault state, if the bypass fails or the bypass voltage is abnormal when the output is not overloaded, except for the faults which

can cause turn-off, the UPS will transfer to the inverter for supply power, such as radiator over-hot. However, if the bypass fails

or the bypass voltage is abnormal when the output is overloaded, the UPS will not transfer to the inverter for supply power, and

will turn off the bypass.

1.5.6 Maintenance Bypass Mode

If maintenance and repair for the UPS are needed, you can switch the load to the Maintenance Bypass through the

maintenance bypass MCB, and the power to the load is not interrupted. The maintenance bypass MCB is located on

the front panel of the POD, and the capacity meets the requirements of the total load capacities. Refer to Liebert® ITA

10kVA UPS Parallel Power Distribution Unit User Manual for the detailed introductions of the POD.

1. The UPS should be installed by an Emerson-authorized engineer according to the information contained in this chapter. If any

problem is found, please get in touch with Emerson local service center immediately.

2. The UPS shall not be powered on without approval of the commissioning engineer.

3. The UPS installation must be carried out by professionals strictly. For other equipment which is not introduced in this manual,

the detailed information about mechanical installation and electrical installation are delivered with the equipment.

2.1 Unpacking Inspection

After the UPS arrival, you should unpack it and check the following items:

1. Visually inspect the UPS appearance for transportation damage. If any problem is found, please notify the carrier

immediately.

2. Check the accessories and models against the delivery list. If any problem is found, please notify the dealer

immediately.

2.2 Installation Preparation

2.2.1 Location

To extend the UPS life, the chosen place must offer:

 Convenient wiring

 Adequate operator access area

 Good ventilation to meet the heat dissipation requirements

 No corrosive gas, like sulfur dioxide

 No excessive moisture or heat source

 No excessive dust

 Compliance with fire-fighting requirements

 Operating temperature compliant with the specifications, see Table 1-2 for details

2.2.2 Environmental Requirements

UPS room

The UPS is designed for indoor installation, which should be installed in a clean and well-ventilated environment, to

keep the environmental temperature within the specifications.

The internal fans provide forced air cooling for the UPS. Cooling air enters the UPS through the ventilation holes on

the rear panel, and exhausts the hot air through the front ventilation holes. Therefore, do not obstruct the ventilation

holes. Maintain at least 200mm clearances between the front, rear, top, bottom, side panels of the UPS and the wall

or adjacent equipment (see Figure 2-1), to avoid obstructing the UPS ventilation and heat dissipation. Otherwise, the

UPS internal temperature will rise, which will shorten the UPS life.

If necessary, an indoor exhaust fan should be installed to keep the indoor temperature from rising. An air filter should

be used in a dusty environment where the UPS is to be operated.

Note

1. The UPS should be installed only on the concrete surface or other non-flammable surfaces.

2. As shown in Figure 2-1 (top view), the demonstration of the clearance between the rear panel of the cabinet and the wall is

500mm. The clearance should not be less than 200mm, it needs to be considered according to the actaul situation for the sake of

maintenance convenience.

Battery room

A small amount of hydrogen and oxygen will be generated at the end of battery charging, therefore, you must ensure

that the fresh air ventilation of the battery installation environment meets the EN50272-2001 requirements.

The battery ambient temperature should keep constant, because the ambient temperature is the main factor to affect

the battery capacity and life. The battery standard operating temperature is 20°C, operation above this temperature

will shorten the battery life, and operation below this temperature will reduce the battery capacity. If the battery

average temperature in operation rises from 20°C to 30°C, the battery life will be reduced by 50%; if the battery

temperature in operation exceeds 40°C, the battery life will be decreased exponentially. In general, the allowable

environmental temperature of the battery is 15°C ~ 25°C. The battery should be kept away from heat and ventilation

holes.

When the UPS uses an external battery, you must install a battery protective device (such as a fuse or a circuit

breaker) in areas near the battery, and use the shortest wiring distance for the connection between the protective

device and the battery.

10 Chapter 2 Single UPS Installation And Commissioning

Liebert® ITA 10kVA UPS User Manual

Storage environment

When the UPS does not need to be installed immediately, the UPS must be stored indoors to be protected from the

excessive moisture or overtemperature environment. The battery requires dry and low temperature, well-ventilated

environment for storage, and the most suitable storage temperature is 20°C ~ 25°C.

Warning: battery hazards

During the battery storage, the battery must be periodically charged according to the battery instructions. When the battery is

charged, you can connect the UPS to the mains temporarily to charge and activate the battery.

2.2.3 Installation Tools

Prepare installation tools according to Table 2-1. The tools must be insulated and ESD-proof processed prior to use.

2.3 External Protective Devices

The circuit breaker or other protective devices must be installed at the external AC input end of the UPS. This section

provides the general guidance for qualified installation engineer. The qualified installation engineer should learn about

the local wiring regulations and other related information.

2.3.1 Battery Input

If the battery module option is provided by Emerson, the battery module has a built-in overcurrent protective device.

Otherwise, the external battery cabinet should equip a DC compatible circuit breaker to provide overcurrent protection

for the UPS and its batteries.

2.3.2 UPS Output

A protective device must be installed for the UPS output power distribution. The protective device must be different

from the input power distribution protection air breaker, and should provide overload protection (see Table 2-4).

2.4 Mechanical Installation

Two installation modes are available: tower installation and rack installation. You can select an appropriate installation

mode according to the actual conditions.

2.4.1 Tower Installation

1. Adjust the display panel.
